Bitcoin ETFs have seen an incredible resurgence in June, with most funds generating billions of dollars in inflows. Overall, the collective of BTC exchange-traded funds has gathered $4.6 billion in June, making it the third-best performing month in 2025.
As usual, that market movement was led by iShares Bitcoin Trust (IBIT), which alone was responsible for $3.85 billion in Bitcoin entering the fund. Fidelity Wise Origin Bitcoin Fund (FBTC) came in second place with $354 million added in June, followed by Bitwise Bitcoin ETF (BITB) with $199 million in inflows.
Grayscale Bitcoin Trust (GBTC) ended the month on a net-negative performance. Overall, the fund registered $34 million in outflows, adding up to a now long history of outflows by Grayscale’s Bitcoin ETF. The fund, which initially converted to a spot ETF in January 2024, has seen over $18 billion in cumulative outflows since then, mostly because Grayscale’s GBTC charges a 1.5% management fee, which is significantly higher than the 0.2%–0.3% range offered by rivals like BlackRock’s IBIT and Fidelity’s FBTC.
IBIT Leading The Charge
IBIT saw a growth of around 3% in market price, reinforcing even further its role as the leading Bitcoin exchange-traded fund. By July 1st, iShares Bitcoin Trust now holds $74.89 billion in net assets, and has pulled in over $52 billion in cumulative inflows since its January 2024 launch.
To put it in perspective, IBIT has only registered two days of outflows in June, and has consistently reported inflows since June 9. Even when Bitcoin slipped below $99,000 on June 22, IBIT continued to accumulate $BTC, adding $217 million on that exact date.
